Reduced sleep may increase energy intake Why1 #371710

CONTEXT(Help)

Tackling obesity in the UK »Tackling obesity in the UKTackling obesity in the UK☜With concern growing that the Foresight analysis—that 50% of the UK population could be obese by 2050, at an annual cost to the nation of around £50 billion per year [2]—substantially underestimates the scale of the unfolding obesity crisis, the College of Contemporary Health is working with the wider policy community to develop a whole systems map of the obesity crisis and the potential responses.☜F1CEB7

Causes of obesity »Causes of obesityCauses of obesity☜Understanding the causes of obesity is critical to the success of prevention and treatment strategies. However, while (simply put) obesity occurs when energy intake from food and drink consumption is greater than energy expenditure through the body’s metabolism and physical activity over a prolonged period (resulting in the accumulation of excess body fat), in reality many complex behavioural and societal factors contribute systemically to the current crisis and no single influence dominates.☜5CD992

Industrial way of life is obesogenic »Industrial way of life is obesogenicIndustrial way of life is obesogenic☜Rapid societal changes—for example, in food production, motorised transport and work/home lifestyle patterns—have placed human physiology (which has evolved to cope with an under-supply of food and high energy expenditure) under new stresses, and revealed an underlying genetic tendency to accumulate and conserve energy (i.e. gain weight) in a high proportion of the population. In this sense, obesity can be construed as a normal physiological response to an abnormal environment.☜5CD992

Reduced sleep »Reduced sleepReduced sleep☜Emerging evidence suggests that people who get insufficient sleep have a higher risk of weight gain and obesity than people who get seven to eight hours of sleep a night.☜5CD992
